[Linux-ia64] Problem solved (was: disabling nics in efi.)

[Roy Dragseth]

Hi.

HP-Support suggested that we tried to disable something called the spanning 
tree algorithm on the switch.   We did, and voila the problem disappeared.  
The spanning tre algorithm has a very long timeout, 30 seconds.

So, for our part the problem is solved, but the timeout issue might be worth 
solving on a general basis.

Thanks for all the insightful suggestions from you people on this list.  This 
problem might be a bit mundane and not very ia64 specific, compared to what 
I've seen on this list before, so I'm sorry if this thread has wasted 
knowlegdable peoples time.

Regards,
Roy.

AFAIK the 30 seconds timeout is derived from the ISO/IEC 10038 standart.
You can probably lower it on the switch your'e using. 

BTW, note that if you've disabled STP alltogether you lost loop
detection on the LAN. This may or may not be a problem but it's
something to keep in mind.

Hope this helps,
Gilad.
